Scroll down to "Web Cameras and Pocket Video Cameras" - http/support.creative.com/kb/showarticle.aspx?sid=61105 - and see if you find your model. Click on "Driver" if you see the model of your webcam. If you don't see your model then there is no Windows 7 driver available.
Do you have a question? If yes, you are more likely to get help if you start your own thread and ask a question. I assume you are looking for some type of webcam driver. If that is true, have you checked the Acer site under support and downloads?
